That's entirely your perception, pal. Nobody said "they're the only ones," or "we had it the worst!" The fact that you think it's "bitching and moaning" to take issue with problems today tells me you don't understand at all.
And as you and I have BOTH said, this is something that continues to this day! You even said those exact words! FFS, people are supposed to stop talking because it's not as bad as it once was? When it was once slavery and genocide, that gets you nothing!
Also, you're being rather hypocritical. You're saying in one breath that people should shut up. Then you're spouting this "we had it worse" line, and then saying you don't care. These are contradictory statements, and they all come down to a selfish attitude.
Truth is, I don't believe your claims about being part Black or part Cherokee. You're clearly lying to peddle this white anger crap. Frankly, it disgusts me.
